T0 all'whmn it'may concern:

Be it known thatI, ANDREW J ARTHUR, a citizen of the United States, residing at Salem,in the county of Dent and State of Missourifhave invented'a'new and useful Separator, of'which the following is a specification.

This invention'relates to gyratory separators or sleves for cleamng, grading, and separating grain, bolting flour, and for all other purposes't'o which sieves, sifters, or separa- "tors ofthis class may be applied.

Inmachines of this class it is of g'reat'importance that the frame carrying the sieve orsifterbe'moved' or operated in such a mannerthatits movement'shall be subjectedto sundry-jerks or interruptions in order that the "material supported-upon the sieve "may bethoro'ug'hly'shaken 0r agitated in orderfto enable thefinerparticles topass through'the meshes of the sieve, thereby accomplishing the'desired separation. "Ordinary gyratory sieves are: constructed primarily with this end inview,'they having been found practically moreeflicient than sieves that are subjected to'a near reciprocatorymovement, for the obvious'reasonthat a yratory sieve is moved 'l'aterally'as wellas longitudinally, while an ordinary reciprocatory sieve is subjected't'o longitudinal movement only.

The object of the-present invention isto increase the efliciency ofthe gyratory movement by first subjecting the movement to a continued'series of interruptions, and, secondly, by combining the gyratory movement whichtakes place inan approximately horizontalplane with a vertically-reciprocatory movement, thereby reatly increasing the capacity for work and the general efficiency of the sieve or separator subjected to such'movement. Other objects of the invention "are -to simplify and improve the construction andoperation of this class of devices.

With'theseand'other ends in view, which will readily appear as'the'nature ofthe'inven tion is better understood, the same consists intheimproved construction andnovel arrangement and combination of arts, which will be hereinafter fully describe and particj -u'lar'lyointed out in the claims.

In t e accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitationis necessarily made to the precisestructu'ral details therein'exhibited, but that changes, alterations, and modifications made when desired. v p

Upon asuitablebase 1, whichmay be' of any de'sired'size and shape"ac cordin'g to the size, shape, and character of thesieve ors'parato'r, there are supported fo'ur telumas or upri hts 2 2, which arepreferably disposedat the ibur corners of "a square or a rectangle. U on the said, uprights near their liiw'r ends, "arejournal'ed' disks or pulleys 3 Sfalll of-which are driven in the same directiOm asLby meaifS of abelt 4, fromadriving iilley '5, apen a shaft6, which latter may 'edrivenyashy means of a belt *7,from'-the source ofpo'wer. (Not shown.) v A tightening-pulley s myee provided for the purpos'e of ie'epin'g the'belt 4 at the'requisite'degree oftension.

Upon'theupper' ends of the 'u' rights-'2 2 are supported disks a'hmngbeve ed orslloping upper sides 10, it being iinders'too'd-that 'the'upperside's or faces of th'e' s'ai'df disks are all sloped or inclined in the same directiiih. These diskss'upportand affoi'dtracks forthe legs or supporting members '1 1" of th'e siftrframe 12. Tlieseiv'eonsifter does'notappear in the drawings,in'asmuch a'sit formsihb part of thepres'eht invention; butitwill be understood that a sieve, sitter, or fisepaaiter of any desired character or construction'may be used in COIiilCti'Oil With "this device, and that such sieve, sifterforseparator istohe suitably supported Wipoh o' r connected with the frame 12. 'It'is desiredj fiirtherhiorefto be understood that it is not hec'essary that the sifter fr'ame 1 2be' supportedin a'horizohtal plane. It is frequently; desirable to give to said frame a p'rohounced slant, *ahd may be readily accomplished 'b'y properly regulating the length of the legs l or'siipportin me'mbers "11, V

The upper ends of the legs or *s uppe'rtifig members 11 have pivotal comiectioh' with.

within the scope of the mantra be .race. mounted a cap 20, which may be secured in the frame 12, preferably at the four corners of said frame, so that they may serve in part to connect the members of which said frame is constructed. If desired, the supporting members 11 may be provided with collars 14, each of said collars having an annular groove 14, in which may be seated antifriction-balls 15, engaging a groove or ball-race 16 in a collar or disk, as 17, u on the under side of the frame. however, be dis ensed with at the discretion of the builder 0 the machine.

Upon the upper sides of the disks 9 are 'secured annular bands 18, having inclined upper and lower faces, the upper faces of said ands being parallel to the inclined faces 10 of the disks 9. The inner sides or walls of said bands are polygonal and have in the drawings been illustrated as being octagonal, this being the referred form. Upon the disks 9, within tlie bands 18 and concentric with the latter, are mounted blocks, as 19, which are polygonal, preferably octagonal, in cross-section, so that between the outer walls of the block 19 and the inner walls of the band 18 there will be formed a polygonal, in the present instance an octagonal, track or Upon each of the blocks 19 there is position as by means of a screw 21 and dowels 22, said cap being poly onal in cross-section and extended beyond t e walls of the block 19. A crown-band 23 is bolted or otherwise secured upon the upper edge of each of the bands 18, said crown-band being provided with inner polygonal walls overhanging the polygonal wall of the band 18 and corre- .the uprights 2. Each of the legs or supporting members is provided with terminal divergent arms, as 26, which may be provided with sockets, as 27, in which are seated antifriction-balls 28, the latter being adapted to engage grooves which may be formed for their reception in the upper faces of the disks 9, in the outer walls of the blocks 19, in the inner walls of the bands 18, and in the under sides of the caps 20 and of the crown-bands 23,

v 7 said grooves being designated, respectively,

29, 30,31, 32, and 33. In place of the sockets 27 and antifriction-balls 28, however, ordinary antifriction-rollers, as 34, may be used, as shown in Fig. 6 of the drawings, and when such rollers are used in place of the balls the These ballearings may,

Upon the upper faces of the disks or pulleys 3 there are supported posts or uprights 35, which are rigidly connected with said disks and which are provided at their upper ends with arms or brackets 36, extending into and engaging vertical slots 37 in the legs or supporting members 11.

The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings heretoannexed. When the device is in operation, the posts or uprights 35 will move orbitally around the casing's comprising the members 9, 18, 19, 20, and 23 and which form or constitute the polygonal races for the legs or supporting members 11 of the sieve-frame. The blades or supporting members 11 are enga ed by the arms or brackets 36 of the uprights 35 and are thereby carried around in the tracks or races, thereby imparting a gyratory movement to the sieve-frame supported said legs or supporting members. Owing, however, to the polygonal shape of the races or tracks, the movement will be subjected to constant interruptions or jars, one interruption or jar occurring at each angle of the polygonal tracks, as will be readily understood. Consequently when octagonal tracks are used each orbit will be subjected to eight distinct interruptions occurring as the direction of movement is changed at the angles of the tracks. Nor is this all; but the legs or supporting members and the sieve-frame supported thereby will be additionally subjected to a vertically-reciprocatory movement by traveling up and down the inclined or sloping faces of the disks 9. This vertically-reciprocatory movement may be multiplied, if desired, by sloping or inclining the faces of the disks 9 in diflerent directions.

Having thus described the invention, what is claimed is- 1. An approximately horizontal sieve frame, supporting members for said frame, and polygonal tracks disposed in an approximately horizontal plane for said supporting members.

2. An approximately horizontal sieveframe having supporting members, polygonal tracks disposed in an approximately horizontal plane for said su porting members, and means for engaging t e supporting members and for moving them around the polygonal tracks.

3. Asieve-frame, supporting members pivotally connected therewith, polygonal tracks for said supporting members, and members moving orbitally around the tracks and engaging the supporting members to move the latter in the tracks.

4. A sieve-frame, supporting members pivotally connected therewith, polygonal tracks for said supportin' members, members su ported for orbita movement around t e tracks and having sliding engagement with the supporting members, and means for driving the orbitally-movable members.

5. A sieve-frame, supporting members pivotally connected therewith and having slots, inclined polygonal tracks for said supporting members, and members supported for orbital movement around the tracks and engaging the slots in the su porting members.

6. In a device of the class described, a plurality of uprights or supporting members, driven pulleys upon said uprights, disks supported at the upper ends of the uprights, polygonal bands and poly onal blocks su ported upon said disks, poIygonal crownands and polygonal caps supported upon the bands and the blocks and spaced a art to form polygonal slots, a sieve-frame aving supporting members extending through said slots and provided with antifriction means engagin the adjacent walls, and members supporte by and connected with the driven pulleys and engaging the supporting members of the sieve-frame to carry the latter around the polygonal grooves or tracks.

7. In a machine of the class described, a plurality of casings having inclosed polygonal tracks or races and polygonal slots communicating therewith, a sieve-frame having supporting members extending through the slots into the races and provided with divergent arms or brackets, antifriction members carried by said arms or brackets and engaging the walls of the races, and members supported for orbital movement and engaging the supporting members of the sieve-frame to carry the latter around the tracks or races.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
